Title: Functor Calculus and Precalculus

Abstract: Functor calculi have been developed in a variety of forms and
contexts for
use in algebraic topology and homological algebra.  Examples include the
manifold calculus of Tom Goodwillie and Michael Weiss, Goodwillie's
calculus of homotopy functors, Weiss' orthogonal calculus, and the discrete
calculi for abelian and simplicial model categories developed with Kristine
Bauer and Randy McCarthy.  After reviewing common features of these
calculi, I will show how the discrete calculus tower is constructed and
describe work in progress with Kathryn Hess to identify a general
 framework, inspired by the discrete calculus, that can be used to generate
functor calculi.
